This invention consists in a buckle-frame having a corrugated or toothedcam, and a toothed tongueplate acting in connection therewith, in suchmanner that the strain on the tug causes the tongue-plate to turn thecam, and thus sccurely'clamp the tug between said tongue-plate and aflat portion ofthe buckleframe, and thereby hold the tug mainly bypressure, so that it Vvis n ot liableto be strained or torn by thebuckletongue, as rhereinafter more fully explained.

In the accompanying drawings- E Iis the' tug, and E is the llames-tug. lh A isthe'buckle-framc, having ears a, a, to which 1s pivoted acar'n, b,and opposite to said cam the buckle- 1 fra-me has a wide-cross-bar orplate, c c, tig, Y

. Thetongue d, 3,) is attached to a sliding plate.

D, the upper face of which is provided with teeth, which engage with theteeth of the cam b.

Its operation is as follows:

To shorten or lengthen out the tug, the cam b is turned back, and thisdiseugges iheplate D, so that turned down, and `as strain is broughtupon the tug,

D and tug E securely upon the Cre-bar c c.

The tongue al merely iills the toothed plate D at the desired point onthe tug, andthe tug is held from slipping through the. buckle by theteetlnD and b, and by the clamping-pressure, but mainly Vbythe latter,and in this manner the tug is held without liability' of the strainbrought upon tbetug.

Having thus described my invention', What Lclaim as new, and desire tosecure by Letters Patent, is-,- l
